发明名称 Method for producing sintered magnet and alloy for sintered magnet
摘要 The present invention provides a method for producing a sintered magnet, which can have a sufficient sintered density even when the magnet has a low-R composition. The method is for producing a sintered magnet comprising R (R: one or more rare-earth elements), T (T: one or more transition metal elements essentially comprising Fe, or Fe and Co) and B (boron) as the main components, wherein a starting alloy prepared by strip casting is pulverized to a given particle size to form a fine powder, where the starting alloy comprises discolored deposit 1 on the surface and the area ratio of the discolored deposit 1 is 1.5% or less, the resulting fine powder is compacted in a magnetic field to prepare a compact, and the compact is sintered.
